' United States, residing. at New York city,

county and State of New York, have jointly invented a new and Improved Tooth-Brush,

of which the following is aspecification.

This invention relates to a tooth brush of novel construction which iscomposed essen* tially of a plurality of short bristle bundles arrangedbehind one another, and encompassed by a divisible shell upon theremoval of a portion of which one of the bristle bundles is likewiseremoved. In this way a fresh bristle bundle may be exposed after eachapplication, so that. thebrush comes up to all modern sanitaryrequirements.

The invention also comprises various other features of construction, allas more fully pointed out in the specification and appended claims: 1

In tl e accompanying drawing: Figure 1 is a, si e view partly in sectionof a tooth 2 the tooth brush comprises a continuous breakable casing orshell, which is composed of alternating cylindrical sections 10 andtapering sections 11, the contracted front end of each tapering sectionopening into the annular back 12 of the adjoining cylindrical section.Within the casing constructed as described, there are fitted back of oneanother, a plurality of axially alined bristle bundles 13, the expandedhead of each bundle being tightly grasped by one'of the taperingsections 11, while the main body'of such bundle extends a distance intothe adjoining cylindrical section 10. The casing charged as described,is inclosed by a breakable tubular covering 14, which is provided with ascored circumferential line 15, near the front of each cylindricalsection 10, which sect-ion may likewise be scored at this point. Betweencovering 14 and the several tapering sections 11, there are formedhollow spaces 16, which permit the covering to be here readily broken.

In use, the foremost bristle bundle 13 is encompassed by the foremostcylindrical section 10, so as to be protected against dust andobjectionable contact. The operator now tears through the covering 14at'the foremost hollow 16 and also through the foremost back 12 andremoves the severed portions of the covering and casing, so as to exposethe foremost bristle bundle 13. In this way the brush is ready for useand may be manipulated to clean the teeth. After application, the endsof the covering and'casmg are torn off on the line 15, thus likewisesevering the used up bristle bundle, which is discarded. The bristlebundle next behind will now come to the front, being protected by thenext cylindrical section 10, until the same is torn off prior to thenext application in the manner described. This operation is repeateduntil the entire stick is used up.

It may be stated that in assembling the parts, the casing shaped asdescribed, is laid out flat, the bristle bundles are fitted therein, andthen the casing is rolled up into cylindriical form and connected at itsoverlapping en s.

With the construction shown in Figs. 35, the axially alinedbristlebundles 13' are inclosed within a wrapper 17 to form a core which inturn is inclosed by a separable shell composed of a plurality of nestedcylindrical caps 18 having coniform tips 19, the caps being in turninclosed by a breakable covering 20. The correlation of the parts hereshown, is such that each bristle bundle 13 carries two of the caps 18,of which the front cap is removed prior to operation, while the secondcap is removed subsequent to operation, the second severed cap carryingthe soiled bristle bundle along with it. In this way, the bundles arealternately exposed and removed, so that a new and clean bundle is atall times available.

In Figs. 6 and 7, the construction is similar to that just described,the length of each cap 21 being however equal to the length of eachbristle bundle. while furthermore the caps break lines with suchbundles. Thus the removal of any one cap will cause the removal of onebristle bundle and the exposure of a new bundle, without howeverprotecting said last named bundle against exposure prior to the usethereof, unless otherwise covered in suitable manner.

It may be stated that the device will form a complete and marketablebrush when constructed as shown in Fig. 4, in which case however thewrapper must be of a strength suflicient to impart the necessaryrigidity to the device.

We claim 1. A tooth brush comprising a plurality of bristle bundlesarranged in axial alinement with each other, and of a breakable coveringinclosing said bundles.

2. A tooth brush comprising a plurality of axially alined bristlebundles, a separable shell inclosing the bundles, and a coveringinclosing the separable shell.

3'. A tooth brush comprising a plurality of axially alined bristlebundles, a surrounding shell composed of alternating cylindrical andtapering sections, and a breakable covering that surrounds the shell.

4. A tooth brush comprising a shell composed of a series oflongitudinally alined separable sections, and a series of inclos'edlongitudinally alined bristle bundles, each of the bristle bundles beincarried by an individual shell section, w ereby the detachment of suchsection will efi'ect a simultaneous detachment of its bristle bundle.

5. A tooth brush comprising a continuous breakable shell composed of aseries of cylindrical sections having annular backs and alternatingtapering sections, the contracted front end of each tapering sectionopening into the annular back of the adjoining cylindrical section, aplurality of axially alined bristle bundles having expanded heads, thehead of each bundle being grasped by one of the tapering sections, whilethe main body of such bundle extends a distance into the adjoiningcylindrical section.
